Hi,

I'm trying to get the average if the year = 2009 or 2010 etc ...

I tried to use this this formula but it gives me 0 :

=AVERAGE(IF(YEAR(Table3[Date])=2009,Table3[Pricing]))

Open in new window


Please help.


Thank you so much for your time.

Hello Dido123,

That formula should work but it's an "array formula" and as such you need to confirm with CTRL+SHIFT+ENTER so that curly braces like { and } apear around the formula in the formula bar.

...or use AVERAGEIFS function

=AVERAGEIFS(Table3[Pricing],Table3[Date],">="&DATE(2009,1,1),Table3[Date],"<"&DATE(2010,1,1))

I would move the IF statement to the outter clause.

=IF(YEAR(Table3[Date])=2009, AVERAGE(Table3[Pricing]), "Whatever to do if not 2009")

Have not tested that code - but if you supply an excel doc. would be able to have a look in detail.

I am not sure about your YEAR(Table3[Date]) part... would need to see the excel document to commment further

I think that the problem with your approach is the cells that are not from 2009 are still included in the AVG calculation.

You may have better luck using a combination of SUMIF and COUNTIF functions instead of AVERAGE.

You'll need to replace date-column-range and pricing-column-range with the proper range expression.

=( SUMIF(date-column-range, 2009, pricing-column-range) / COUNTIF(date-column-range, 2009) )

Hello Oblivion SY,

That won't work I'm afraid - Dido's syntax is OK as I say - it just needs array entering.

sjklein42. The use of YEAR in the formula suggests that the Date field contains a date so you can't use just 2009 in a SUMIF criteria, that won't sum anything.....

See attached for examples of my two suggestions above and a third option which allows you to put the year in a cell I1 and use

=AVERAGEIFS(Table3[Pricing],Table3[Date],">="&DATE(I1,1,1),Table3[Date],"<"&DATE(I1+1,1,1))

...on second thoughts....perhaps you are correct sjklein42, apologies. If there is just a year in the date column then that would be consistent with the formula producing a zero result. If that is the case then you can use sjklein's SUMIF/COUNTIF suggestion or AVERAGEIF like

=AVERAGEIF(Table3[Date],2009,Table3[Pricing])
